When testing email notifications from Campaigns if a user is included in the Test; for example email@example.com and doesn't receive the email notification when the Campaign goes live.
The reason why is because they received the test email notification and the same Campaign and Segment were used. How to prevent this from occurring:
- Use a Test Campaign
- Use a Test Segment
- Tester (firstname.lastname@example.org) will receive test email notification
- When actual Campaign fires the tester will also receive the actual email notification from the Live Campaign.
